Description
The purpose of this thesis research project is to explore blockchain technology and its present and future applications within supply chain management. Emerging blockchain technologies, both public and private, are already showing great promise for a number of applications in and outside supply chain management. Our sole focus is to understand the fundamentals of blockchain, smart contracts, current applications in supply chain, and the future possibilities for blockchain to shape global supply chains. Many have theorized about how private blockchains can be implemented and used; however, there is little research to date that has collected and explored the actual use cases in industry today. The mission of this research paper is to separate theory from the current state of the technology and provide a clearer understanding of where the technology is headed in the near future. We aim to produce a work that will provide a comprehensive description and commentary on current use cases for the education of students and industry professionals alike. With any new technological developments, terminology and technicalities can be paralyzing, and this is particularly true for blockchain technology. For this project, our goal was to create a document that cuts through the complexities and allows a non-technical audience to gain a strong foundational understanding of blockchain's potential and current limitations within supply chains. Provided this, some highly technical concepts and implementation details will not be explored due to the complexity and minimal understanding even amongst industry experts. As future supply chain professionals, we are motivated to further our understanding of blockchain technologies and the potential for this technology to shape the future of supply chain management.

Description
Security requirements are at the heart of developing secure, invulnerable software. Without embedding security principles in the software development life cycle, the likelihood of producing insecure software increases, putting the consumers of that software at great risk. For large-scale software development, this problem is complicated as there may be hundreds or thousands of security requirements that need to be met, and it only worsens if the software development project is developed by a distributed development team. In this thesis, an approach is provided for software security requirement traceability for large-scale and complex software development projects being developed by distributed development teams. The approach utilizes blockchain technology to improve the automation of security requirement satisfaction and create a more transparent and trustworthy development environment for distributed development teams. The approach also introduces immutability, auditability, and non-repudiation into the security requirement traceability process. The approach is evaluated against existing software security requirement solutions.

Description
Large organizations have multiple networks that are subject to attacks, which can be detected by continuous monitoring and analyzing the network traffic by Intrusion Detection Systems. Collaborative Intrusion Detection Systems (CIDS) are used for efficient detection of distributed attacks by having a global view of the traffic events in large networks. However, CIDS are vulnerable to internal attacks, and these internal attacks decrease the mutual trust among the nodes in CIDS required for sharing of critical and sensitive alert data in CIDS. Without the data sharing, the nodes of CIDS cannot collaborate efficiently to form a comprehensive view of events in the networks monitored to detect distributed attacks. The compromised nodes will further decrease the accuracy of CIDS by generating false positives and false negatives of the traffic event classifications. In this thesis, an approach based on a trust score system is presented to detect and suspend the compromised nodes in CIDS to improve the trust among the nodes for efficient collaboration. This trust score-based approach is implemented as a consensus model on a private blockchain because private blockchain has the features to address the accountability, integrity and privacy requirements of CIDS. In this approach, the trust scores of malicious nodes are decreased with every reported false negative or false positive of the traffic event classifications. When the trust scores of any node falls below a threshold, the node is identified as compromised and suspended. The approach is evaluated for the accuracy of identifying malicious nodes in CIDS.

Description
The coordination of developing various complex and large-scale projects using computers has been well established and is the so-called computer-supported cooperative work (CSCW). Collaborative software development consists of a group of teams working together to achieve a common goal for developing a high-quality, complex, and large-scale software system efficiently, and it requires common processes and communication channels among these teams. The common processes for coordination among software development teams can be handled by similar principles in CSCW. The development of complex and large-scale software becomes complicated due to the involvement of many software development teams. The development of such a software system can be largely improved by effective collaboration among the participating software development teams at both software components and system levels. The efficiency of developing software components depends on trusted coordination among the participating teams for sharing, processing, and managing information on various participating teams, which are often operating in a distributed environment. Participating teams may belong to the same organization or different organizations. Existing approaches to coordination in collaborative software development are based on using a centralized repository to store, process, and retrieve information on participating software development teams during the development. These approaches use a centralized authority, have a single point of failure, and restricted rights to own data and software. In this thesis, the generation of trusted coordination in collaborative software development using blockchain is studied, and an approach to achieving trusted cooperation for collaborative software development using blockchain is presented. The smart contracts are created in the blockchain to encode software specifications and acceptance criteria for the software results generated by participating teams. The blockchain used in the approach is a private blockchain because a private blockchain has the characteristics of providing non-repudiation, privacy, and integrity, which are required in trusted coordination of collaborative software development. This approach is implemented using Hyperledger, an open-source private blockchain. An example to illustrate the approach is also given.

Description
Many researchers have seen the value blockchain can add to the field of voting and many protocols have been proposed to allow voting to be conducted in a way that takes advantage of blockchains distributed and immutable structure. While blockchains immutable structure can take the place of paper records in preventing tampering it by itself is insufficient to construct a trustworthy voting system with eligibility, privacy, verifiability, and fairness requirements. Many of the protocols which strive to keep voters votes confidential, but also allow for verifiability and eligibility requirements rely on either a blind signature provided by a central authority to provide compliance with these requirements or ring signatures to prove membership in the set of voters. A blind signature issued by a central authority introduces a potential vulnerability as it allows a corrupt central authority to pass a large number of forged ballots into the mix without any detection. Ring signatures on the other hand tend to be overly resource intensive to allow for practical usage in large voting sets. The research in this thesis focuses on improving the trustworthiness of electronic voting systems by providing possible ways of avoiding or detecting corrupt central authorities while still relying upon the benefits of efficiency the blind signature provides.

Description
The purpose of this thesis is to imagine and predict the ways in which humans will utilize technology to feed the world population in the 21st century, in spite of significant challenges we have not faced before. This project will first thoroughly identify and explain the most pressing challenges the future will bring in climate change and population growth; both projected to worsen as time goes on. To guide the prediction of how technology will impact the 21st century, a theoretical framework will be established, based upon the green revolution of the 20th century. The theoretical framework will summarize this important historical event, and analyze current thought concerning the socio-economic impacts of the agricultural technologies introduced during this time. Special attention will be paid to the unequal disbursement of benefits of this green revolution, and particularly how it affected small rural farmers. Analysis of the technologies introduced during the green revolution will be used to predict how 21st century technologies will further shape the agricultural sector. Then, the world’s current food crisis will be compared to the crisis that preceded the green revolution. A “second green revolution” is predicted, and the agricultural/economic impact of these advances is theorized based upon analysis of farming advances in the 20th century.

Description
This study aims to examine how the use of consensus-based transactions, smart contracts,and interoperability, provided by blockchain, may benefit the blood plasma industry. Plasmafractionation is the process of separating blood into multiple components to garner benefitsof increased lifespan, specialized allocation, and decreased waste, thereby creating a morecomplex and flexible supply chain. Traditional applications of blockchain are developed onthe basis of decentralization—an infeasible policy for this sector due to stringent governmentregulations, such as HIPAA. However, the trusted nature of the relations in the plasmaindustry’s taxonomy proves private and centralized blockchains as the viable alternative.Implementations of blockchain are widely seen across pharmaceutical supply chains to combatthe falsification of possibly afflictive drugs. This system is more difficult to manage withblood, due to the quick perishable time, tracking/tracing of recycled components, and thenecessity of real-time metrics. Key attributes of private blockchains, such as digital identity,smart contracts, and authorized ledgers, may have the possibility of providing a significantpositive impact on the allocation and management functions of blood banks. Herein, we willidentify the economy and risks of the plasma ecosystem to extrapolate specific applications forthe use of blockchain technology. To understand tangible effects of blockchain, we developeda proof of concept application, aiming to emulate the business logic of modern plasma supplychain ecosystems adopting a blockchain data structure. The application testing simulates thesupply chain via agent-based modeling to analyze the scalability, benefits, and limitations ofblockchain for the plasma fractionation industry.

Description
Blockchain technology has the potential to be an effective form of identity management and human trafficking prevention as an identity solution. The topic of this thesis originates from the United Nation’s Sustainable Development Goal to create a form of identity for every individual on the plant by the year 2030. This research analyzed and compared primarily global databases with information on human trafficking populations and unidentified populations to understand both issues, and the intersections of their populations. This is followed by a discussion of Blockchain technology’s attributes and a Blockchain identities potential characteristic. This research concludes that a Blockchain based identity can be used to mitigate human trafficking by creating various forms of identity for affected populations. Four basic factors of Blockchain technology can be utilized through public and private partnerships to address different parts of the AMP model for the cycle of human trafficking. The conclusion that Blockchain is a potential solution to the analyzed issues comes with caution and alongside an examination of the risk factors involved in implementing this technology and the future investigation necessary to test this conclusion. Risk factors with using blockchain technology as a solution are examined to help direct future research on the topic. The conclusion is based off Blockchain’s ability to address specific problems in human trafficking and the global identity crisis (GIC) that were found in the analysis.

Description
The purpose of this research paper is to examine the fundamentals of blockchain technology and how the application of blockchain could serve as a future platform for identity. An identity is used, as the name suggests, to identify who or what an entity is. Although seen as a trivial concept, defining what truly makes up an identity can become quite difficult. Is an identity the thoughts, feelings, or tendencies of a person? Are more tangible assets like a Social Security card, birth certificate, or passport a person’s identity? Can nonhuman entities like businesses or organizations possess an identity? The true definition of an identity may never be known; however, it is certain that several pieces of identifying data lay scattered across multiple databases. Often a person may not have control or even access to these third-party databases that hold their information. Moreover, what information, for how long, and in what way the data is being used may be unclear. Blockchain provides a solution to the identity problem by providing a visible, secure single source of truth. On a blockchain platform, a person would no longer have to trust the goodwill of third parties to secure their data or be uncertain about how the data is being used. Instead, a user could secure their own data and only permission those deemed necessary. The signal immutable ledger would serve to replace current tangible identities as a means to verify yourself in a digital age.
